Improve error clarification

[ju]

Errors are currently unclear and provide little insight into the potential causes of failed operation attempts.

For an example: Error processing script: No such file or directory (os error 2) is an error I face while attempting to use the april-fools operation and have not been able to figure out the root cause of this issue.

The environment variable RUST_LOG unfortunately gives no useful information for errors. If possible, including the full backtrace result for ScriptError exceptions or a verbose option during operation would be great as well.
